d ,VEHCLEWHEEL-W resident of Memphis, in the county of Shelby and State of Tennessee,l have invented a new e y iand'lmproved.Vehicle-Wheel, of which the y `following is a full, clear, and enact descripson.` s Thisy invention relates to vehicle-wheels,

land more particlarly to suchas areportionsl and exceedinglystrong'is well adapted for y,convenient re air, :is Fnotliable to becomev E cloggedwithc ay or the like Whenthe Wagon is traversing muddy roads, and l is manu actured of n1etal,'-'and largely fromwplated metal cut and stamped into form, .whereby it is adapted lowcost.- l E v The inventlonconsists -.1n the novel construction andcombination of parts, as herein'after described, anddefined inthe subjoined clainis.- v v -1 R ference is tobe `had'to the accompanying'drawing forming a part of this specificahide-Wheel."r `Fi 2 is a` central transverse i yss sectional lview su stantially onthe line 2.2'in

Fig. showing the interior construction` of the main 'portion of the wheel'. Fig. j3 is' a ,p fragmentary side view -of details, showing y,meansfor' holding-the s indle sleeve or box r .detachabl'y secured on t e frontfwall of the y wheel-body. tis an enlargedperspec- 4o tive view of'fav portion of the periphery and side Wall' of ones'ection ofthew eel-body.

Fig. 5 is-an enlargedsectionalside view of parts shown in Fig.` 3 yand Fig. 6 is a transatire shown secured therein. V y i In the drawings, `1() 10l represent two 5 verse sectional view of `a portion ofthe body of the improved wheel', 'showing a 'slightly- 4modified form of the two sections of the wheeli body, which adapt them kfor the reception of sentia-lly y concavoconvexforrn in transverse section, as al pearsin'Fi 42. "Each half-section 10 0f t e wheel-bo yxis centrally'apertured, and as aborder for said apertre an invfor'rapid and perfect production at a double thickness @tions 10', as appears in yNear theyperiphery ofthe two-part wheeli body there 1s va series of' spaced perforatons l l simi-` "formed in pairs oppositely disposed therein lar body portions of the improved wheel each p consisting of a plate-metal disk that is dished., Y a` suitable degree, thusgiving the same anes-" y tegral'flange Q10' isturnediinwardlyat an acute.. angle fromy the concave side` thereof,

the aperture in the disk forming lthe normallyT outer sidewall of the wheel having its-'diameter reduced a suitable degree with relation to' ythat in the other side wall that is innermost in service;y yThere is a flange 1'0b formed on z the periphery of each half-section` 10, which anges are tu'rned inwardly at an obtuse anle, and as these circular flanges have an equal iameter ity willbeseen that when they h ave proper engagement at Ltheirinner edges the outer surfaces of saidflanges will coincide and form a true periphery or rim-surface for theWheeLU.'

As shownin Figs.- -2 and 4, thev flanges 10b are each formed with a series of tongues a by slittin theri'm-flanges `at suitableintervals `frornt eir inner edges,'and said ton u'es on each rim 10b' are Vs aced apart/a istance equal tothe width-,o the tongues.l e

The ton ues, as shown, are offset near their points of'junctionA with the rim-flan e '10b theyy are formed on, sothat vthey may e slid 8o beneath intervening straight members, asis clearly shownin Fig. 2,- thus adapting the rim-flanges at their tongues tohavean interf vlocking'engagement -with each other and together form a practically continuous rim of tioned;

provided as a h properk degree from the normally inner to the outer'end thereof, having correspondinglytapered bearings of increased diameter formed thereonat respective ends, which bearings fit l E closely'intb-t e openings defined' by thein'- wardly-tu'rned annularflangesl u The length of the thimble is so propor-4 tioned that ,when the wheel half-sections 10v 'are joined together the true ends of the thimble' orbox'v 11 will be disposed flash withthev exterior surfaces; of theplate-rnetal half-secvlgs.v 2 and 5,.

which receive acorresponding number'` of rodwhere' the tongues are posin ICD IOS l `like clamping-bolts b, that are designedv to khold the body-.sections 10 drawn forcibly toyget her, andto this end` one Vprojecting ei;-

tremitvof each `bolt is -headed and the other end/ after insertion, is. riveted,to facilitate whichk said 'ends may be heated.

l erably having hook-shaped heads c formed upon their inner ends, and u on the exterior of the thimble at a suitable istance from its ends lugs c are formed thereon, which are engaged by said hooks. The tie-bolts are so proportioned in length that their remaining ends may be passed out through perforations in the half-section 10 of the body' that is outermost in service. Each bolt end which projects through the body portion 10 is threaded, and a nut d is screwed thereon into forcible contact with the exterior surface of said body-section, thus drawing upon and holding the thimble in place.

To prevent a loosening of the nuts d, a hubplate 13 is provided, this plate having an annular form, a central bore therein of slightly greater diameter than that of the adjacent end of the thimble 11', and also furnished with a series of cup-like recesses d', which receive and loosely incase the nuts d. Furthermore, the nuts may be held from turning by pouring melted lead through perforations d2 into said. recesses around the nuts, as shown in Fig. 2, or into the open ends of said recesses. (RepresentediinFig. 5.') Upon theflangesl()a metal bands 10 are shrunken,- which render the flanges more rigid, reinforcing the hub portions of the wheel against shocks sustained thereby due to impact of the Wheelrim on the rough surface of a road-bed over which the wheel is moved in service.

Opposite the reinforcing-band 1()C on the inner flange 1()a a mud-guard in the form of a flanged ring 14 is mounted and secured upon the rear body-section 10 by means of rivets or screw-bolts which engage perforations in the flange 14a of said ring and alined perforations in the body-section' mentioned, the mudard being held concentric with the thimle 11. The thimble is rendered true on the inner surface by reaming it with a suitable tapering tool or by other means, thus giving its inner wall a truc coniform taper, which adapts it to serve as a box for the reception therein of a correspondingly-tapered body of an axle-spindle 15, which is a portion of a wagon-axle 15. Should the axle be formed of wood and the spindle also, the usual skein or metal bearing may be mounted upon and secured to the axle-spindle, thus providin y a suitable bearing thereon, the spindle in this case beinor reduced in diameter proportionately. Tliey outer end portion of the'spindle 15a is reduced in diameter and threaded for reception of a nut- 15", which bears at its inner end upon the outer end of the thimble 11, as shown in Fig. 2, thus holding the spindle operatively engaged with the thimble.

In thev wheel hereinbcfore described' thc wheel is not provided with a separate tire, the material forming the flanges 10b having a .upon is secured in place b thickness that adapts, these connected flanges to afford a substantial rim for the wheel. When it is desirable to place a reinforcingtire upon the wheel-rim, the flanges on the wheel-rim are left devoid of tongues, and on their flat exterior surface a tire-ring 16 is closely fitted and after it is mounted7 therebolts or rivets, the provision of the tire-rmg adapting the improved wheel for service on a wagon used for transporting freight over a rough roadbed.

It will be seen that in view of its strength and load-bearing capacity the improved vehicle-Wheel is very i ht, may be formed of `steel or iron, is excee ingly well adapted for supporting load strain, and may by suitable means be constructed rapidly and perfectly at a'low cost. Furthermore, the improved vehicle-wheel may be given any size and its parts be proportioned to suit light or heavy service, thus adapting the improvement for use as parts of running-gears for coaches or other passenger-carrying vehicles.
